I mean literally - when there is something in life that puts a smile on your face or brings you a little bit of joy, make note of it somewhere.
Like this morning.
Every morning, I go let the dog out of Devin's room to feed her and let her out before I go to work. Some mornings, Devin stays asleep.
This morning, she sat straight up with a huge smile and said, "I had the best dream in the world!"
"Oh, yeah?"
"Yeah! I saw a...rainbow...BUTTERFLY!!!"
Literally, write stuff like this down. Life is full of little moments like this. Make note of the good ones
